## Usage
### Setup Overview
#### Authentication Methods
The server supports four authentication methods:
**For local/desktop use** (most common):
1. **Personal Access Token** (`GITLAB_PERSONAL_ACCESS_TOKEN`) — simplest setup
2. **OAuth2 — Local Browser** (`GITLAB_USE_OAUTH`) — recommended for better security
**For server/remote deployments**:
3. **OAuth2 — MCP Proxy** (`GITLAB_MCP_OAUTH`) — for remote MCP clients such as Claude.ai
4. **Remote Authorization** (`REMOTE_AUTHORIZATION`) — multi-user deployments where each caller provides their own token
#### Quick setup paths
- **Claude Code**: see [Claude Code Setup Guide](./docs/claude-code-setup.md)
- **VS Code**: see [VS Code Setup Guide](./docs/vscode-setup.md)
- **GitHub Copilot**: see [GitHub Copilot Setup Guide](./docs/copilot-setup.md)
- **Codex**: see [Codex Setup Guide](./docs/codex-setup.md)
- **Cursor**: see [Cursor Setup Guide](./docs/cursor-setup.md)
- **Factory AI Droid / OpenClaw / OpenCode style clients**: see [JSON-Based MCP Clients Setup Guide](./docs/json-mcp-clients-setup.md)
- **OAuth browser flow details**: see [OAuth2 Authentication Setup Guide](./docs/oauth-setup.md)
For the simplest local setup, start with a Personal Access Token. For browser-based local auth, use OAuth2. For remote or multi-user deployments, continue to the MCP OAuth and Remote Authorization sections later in this README.
#### Using CLI Arguments (for clients with env var issues)
Some MCP clients (like GitHub Copilot CLI) have issues with environment variables. Use CLI arguments instead:
```json
{
"mcpServers": {
"gitlab": {
"command": "npx",
"args": [
"-y",
"@zereight/mcp-gitlab",
"--token=YOUR_GITLAB_TOKEN",
"--api-url=https://gitlab.com/api/v4"
],
"tools": ["*"]
}
}
}
```
**Available CLI arguments:**
- `--token` - GitLab Personal Access Token (replaces `GITLAB_PERSONAL_ACCESS_TOKEN`)
- `--api-url` - GitLab API URL (replaces `GITLAB_API_URL`)
- `--read-only=true` - Enable read-only mode (replaces `GITLAB_READ_ONLY_MODE`)
- `--use-wiki=true` - Enable wiki API (replaces `USE_GITLAB_WIKI`)
- `--use-milestone=true` - Enable milestone API (replaces `USE_MILESTONE`)
- `--use-pipeline=true` - Enable pipeline API (replaces `USE_PIPELINE`)
CLI arguments take precedence over environment variables.

}
}

```
#### Using MCP OAuth Proxy (`GITLAB_MCP_OAUTH`)
> **For server/remote deployments only.** This mode requires the MCP server to be deployed with a publicly accessible HTTPS URL. For local/desktop use, see `GITLAB_USE_OAUTH` above.
For remote MCP clients that support the MCP OAuth specification (e.g. Claude.ai).
The server acts as a full OAuth 2.0 authorization server — unauthenticated requests
receive a `401 + WWW-Authenticate` response, which triggers the OAuth browser flow
automatically on the client side.
Remote MCP clients such as OpenCode, MCPJam, and Claude.ai can send their own
callback URL during authorization. If you cannot register every client callback
URL in GitLab, enable `GITLAB_OAUTH_CALLBACK_PROXY=true`. With callback proxy
mode, GitLab only needs one registered redirect URI: `{MCP_SERVER_URL}/callback`.
`GITLAB_OAUTH_REDIRECT_URI` is for local OAuth (`GITLAB_USE_OAUTH`) only. It does
not override remote MCP OAuth client callback URLs and should not be used to fix
remote `Unregistered redirect_uri` errors.
This variable exists because the local OAuth flow starts a browser on the same
machine as the MCP server and listens for the callback on a local HTTP server,
for example `http://127.0.0.1:8888/callback`.
Remote MCP OAuth is different. In `GITLAB_MCP_OAUTH=true` mode, the MCP client
provides its own callback URL during `/authorize`. `GITLAB_OAUTH_REDIRECT_URI`
does not replace that client-provided URL.
| Mode | Enable with | Callback variable | GitLab redirect URI |
| --- | --- | --- | --- |
| Local OAuth | `GITLAB_USE_OAUTH=true` | `GITLAB_OAUTH_REDIRECT_URI` | `http://127.0.0.1:8888/callback` or your local callback |
| Remote MCP OAuth | `GITLAB_MCP_OAUTH=true` | `GITLAB_OAUTH_CALLBACK_PROXY=true` | `{MCP_SERVER_URL}/callback` |
Use `GITLAB_OAUTH_REDIRECT_URI` only when the MCP server itself owns the local
browser callback. Use `GITLAB_OAUTH_CALLBACK_PROXY=true` when a remote MCP client
owns the callback URL.
**How it works**: You deploy this MCP server somewhere with a public HTTPS URL. MCP
clients connect to `{MCP_SERVER_URL}/mcp`. The server handles the OAuth 2.0 flow,
exchanging credentials with GitLab on behalf of the client.
**Prerequisites**:
1. A publicly accessible HTTPS server URL (`MCP_SERVER_URL`) — use [ngrok](https://ngrok.com) for local testing
2. A pre-registered GitLab OAuth application with `api` (or `read_api`) scopes
— Go to `Admin area` → `Applications`, set Redirect URI to `{MCP_SERVER_URL}/callback`
| Environment Variable | Required | Description |
| --------------------- | -------- | ---------------------------------------------------------- |
| `GITLAB_MCP_OAUTH` | ✅ | Set to `true` to enable |
| `GITLAB_API_URL` | ✅ | GitLab API base URL |
| `GITLAB_OAUTH_APP_ID` | ✅ | GitLab OAuth Application ID |
| `MCP_SERVER_URL` | ✅ | Public HTTPS URL of this MCP server |
| `STREAMABLE_HTTP` | ✅ | Must be `true` |
| `GITLAB_OAUTH_CALLBACK_PROXY` | optional | Set to `true` to use the MCP server's fixed `/callback` URL |
| `GITLAB_OAUTH_SCOPES` | optional | Comma-separated scopes (default: `api,read_api,read_user`) |
When `STREAMABLE_HTTP=true`, server-side `GITLAB_PERSONAL_ACCESS_TOKEN` or `GITLAB_JOB_TOKEN` require `REMOTE_AUTHORIZATION=true` or `GITLAB_MCP_OAUTH=true`.
> **Troubleshooting `Unregistered redirect_uri`**
>
> Check the `redirect_uri` in the browser URL. If it points to a client callback
> such as `http://127.0.0.1:xxxxx/.../callback`, enable:
>
> ```env
> GITLAB_OAUTH_CALLBACK_PROXY=true
> ```
>
> Do not fix remote MCP OAuth by changing `GITLAB_OAUTH_REDIRECT_URI`. That
> variable is for local OAuth (`GITLAB_USE_OAUTH`) only.

MCP client configuration:
```json
{
"mcpServers": {
"gitlab": {
"type": "http",
"url": "https://your-server.example.com/mcp"
}
}
}
```
#### Using Remote Authorization (`REMOTE_AUTHORIZATION`)
> **For server/remote deployments only.** Each HTTP caller provides their own GitLab token directly in request headers — no OAuth flow involved.
For multi-user or multi-tenant deployments where each caller provides their own
GitLab token in the HTTP request header. No OAuth flow — the MCP server forwards
the token to GitLab on behalf of the caller.
**Header priority**: `Private-Token` > `JOB-TOKEN` > `Authorization: Bearer`
| Environment Variable | Required | Description |
| ------------------------ | -------- | ---------------------------------------------------------- |
| `REMOTE_AUTHORIZATION` | ✅ | Set to `true` to enable |
| `STREAMABLE_HTTP` | ✅ | Must be `true` |
| `ENABLE_DYNAMIC_API_URL` | optional | Allow per-request GitLab URL via `X-GitLab-API-URL` header |
**Example request headers**:
```http
Private-Token: glpat-xxxxxxxxxxxxxxxxxxxx
```
or using a Bearer token:
```http
Authorization: Bearer glpat-xxxxxxxxxxxxxxxxxxxx
```
> ⚠️ `REMOTE_AUTHORIZATION` is **not compatible** with SSE transport. `STREAMABLE_HTTP=true` is required.
### Environment Variables
Use the dedicated reference for the full environment variable list:
- [Environment Variables Reference](./docs/environment-variables.md)
Most users only need one of these starting sets:
- **Local PAT**: `GITLAB_PERSONAL_ACCESS_TOKEN`, `GITLAB_API_URL`
- **Local OAuth**: `GITLAB_USE_OAUTH=true`, `GITLAB_OAUTH_CLIENT_ID`, `GITLAB_OAUTH_REDIRECT_URI`, `GITLAB_API_URL`
- **Remote multi-user HTTP**: `STREAMABLE_HTTP=true`, `REMOTE_AUTHORIZATION=true`, `HOST`, `PORT`
- **Multi-pod HPA (stateless)**: above + `OAUTH_STATELESS_MODE=true`, `OAUTH_STATELESS_SECRET` (same across all pods). See [Stateless Mode](./docs/stateless-mode.md).
Commonly referenced variables:
- `GITLAB_API_URL`
- `GITLAB_PERSONAL_ACCESS_TOKEN`
- `GITLAB_USE_OAUTH`
- `REMOTE_AUTHORIZATION`
- `GITLAB_MCP_OAUTH`
- `GITLAB_OAUTH_CALLBACK_PROXY`
- `OAUTH_STATELESS_MODE`
- `OAUTH_STATELESS_SECRET`
The reference document also covers:
- auth and OAuth variables
- MCP OAuth proxy variables
- project and tool filtering variables
- dynamic tool discovery via `discover_tools` (on-demand toolset activation)
- transport and session variables
- proxy and TLS variables
For callback proxy mode details, see [GitLab MCP OAuth Callback Proxy](./docs/oauth-callback-proxy.md).
### Remote Authorization Setup (Multi-User Support)
When using `REMOTE_AUTHORIZATION=true`, the MCP server can support multiple users, each with their own GitLab token passed via HTTP headers. This is useful for:
- Shared MCP server instances where each user needs their own GitLab access
- IDE integrations that can inject user-specific tokens into MCP requests
**Setup Example:**
```bash
# Start server with remote authorization
docker run -d \
-e HOST=0.0.0.0 \
-e STREAMABLE_HTTP=true \
-e REMOTE_AUTHORIZATION=true \
-e GITLAB_API_URL="https://gitlab.com/api/v4" \
-e GITLAB_READ_ONLY_MODE=true \
-e SESSION_TIMEOUT_SECONDS=3600 \
-p 3333:3002 \
zereight050/gitlab-mcp
```
**Client Configuration:**
Your IDE or MCP client must send one of these headers with each request:
```
Authorization: Bearer glpat-xxxxxxxxxxxxxxxxxxxx
```
or
```
Private-Token: glpat-xxxxxxxxxxxxxxxxxxxx
```
The token is stored per session (identified by `mcp-session-id` header) and reused for subsequent requests in the same session.
#### Remote Authorization Client Configuration Example with Cursor
```json
{
"mcpServers": {
"GitLab": {
"url": "http(s)://<your_mcp_gitlab_server>/mcp",
"headers": {
"Authorization": "Bearer glpat-..."
}
}
}
}
```
**Important Notes:**
- Remote authorization **only works with Streamable HTTP transport**
- Each session is isolated - tokens from one session cannot access another session's data
Tokens are automatically cleaned up when sessions close
- **Session timeout:** Auth tokens expire after `SESSION_TIMEOUT_SECONDS` (default 1 hour) of inactivity. After timeout, the client must send auth headers again. The transport session remains active.
- Each request resets the timeout timer for that session
- **Rate limiting:** Each session is limited to `MAX_REQUESTS_PER_MINUTE` requests per minute (default 60)
- **Capacity limit:** Server accepts up to `MAX_SESSIONS` concurrent sessions (default 1000)
### MCP OAuth Setup (Claude.ai Native OAuth)
When using `GITLAB_MCP_OAUTH=true`, the server acts as an OAuth proxy to your GitLab
instance. Claude.ai (and any MCP-spec-compliant client) handles the entire browser
authentication flow automatically — no manual Personal Access Token management needed.
**Prerequisites:**
A **pre-registered GitLab OAuth application** is required. GitLab restricts dynamically
registered (unverified) applications to the `mcp` scope, which is insufficient for API
calls (need `api` or `read_api`).
1. Go to your GitLab instance → **Admin Area > Applications** (instance-wide) or **User Settings > Applications** (personal)
2. Create a new application with:
- **Confidential**: unchecked
- **Scopes**: `api`, `read_api`, `read_user` (or whichever scopes you intend to request via `GITLAB_OAUTH_SCOPES`)
3. Save and copy the **Application ID** — this is your `GITLAB_OAUTH_APP_ID`
**How it works:**
1. User adds your MCP server URL in Claude.ai
2. Claude.ai discovers OAuth endpoints via `/.well-known/oauth-authorization-server`
3. Claude.ai registers itself via Dynamic Client Registration (`POST /register`) — handled locally by the MCP server (each client gets a virtual client ID)
4. Claude.ai redirects the user's browser to GitLab's login page using the pre-registered OAuth application
5. User authenticates; GitLab redirects back to `https://claude.ai/api/mcp/auth_callback`
6. Claude.ai sends `Authorization: Bearer <token>` on every MCP request
7. Server validates the token with GitLab and stores it per session
**Server setup:**
```bash
docker run -d \
-e STREAMABLE_HTTP=true \
-e GITLAB_MCP_OAUTH=true \
-e GITLAB_OAUTH_APP_ID="your-gitlab-oauth-app-client-id" \
-e GITLAB_API_URL="https://gitlab.example.com/api/v4" \
-e MCP_SERVER_URL="https://your-mcp-server.example.com" \
-p 3002:3002 \
zereight050/gitlab-mcp
```
For local development (HTTP allowed):
```bash
MCP_DANGEROUSLY_ALLOW_INSECURE_ISSUER_URL=true \
STREAMABLE_HTTP=true \
GITLAB_MCP_OAUTH=true \
GITLAB_OAUTH_APP_ID=your-gitlab-oauth-app-client-id \
MCP_SERVER_URL=http://localhost:3002 \
GITLAB_API_URL=https://gitlab.com/api/v4 \
node build/index.js
```
**Claude.ai configuration:**
```json
{
"mcpServers": {
"GitLab": {
"url": "https://your-mcp-server.example.com/mcp"
}
}
}
```
No `headers` field is needed — Claude.ai obtains the token via OAuth automatically.
**Environment variables:**
| Variable | Required | Description |
| ------------------------------------------- | -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `GITLAB_MCP_OAUTH` | Yes | Set to `true` to enable |
| `GITLAB_OAUTH_APP_ID` | Yes | Client ID of the pre-registered GitLab OAuth application |
| `MCP_SERVER_URL` | Yes | Public HTTPS URL of your MCP server |
| `GITLAB_API_URL` | Yes | Your GitLab instance API URL (e.g. `https://gitlab.com/api/v4`) |
| `STREAMABLE_HTTP` | Yes | Must be `true` (SSE is not supported) |
| `GITLAB_OAUTH_SCOPES` | No | Comma-separated GitLab scopes to request (e.g. `api,read_user`). Defaults to `api` (or `read_api` when `GITLAB_READ_ONLY_MODE=true`). The pre-registered application must be configured with at least these scopes. |
| `MCP_DANGEROUSLY_ALLOW_INSECURE_ISSUER_URL` | No | Set `true` for local HTTP dev only |
**Important Notes:**
- MCP OAuth **only works with Streamable HTTP transport** (`SSE=true` is incompatible)
- Each user session stores its own OAuth token — sessions are fully isolated
- Session timeout, rate limiting, and capacity limits apply identically to the
`REMOTE_AUTHORIZATION` mode (`SESSION_TIMEOUT_SECONDS`, `MAX_REQUESTS_PER_MINUTE`,
`MAX_SESSIONS`)
- **Header auth fallback:** when `Private-Token` or `JOB-TOKEN` request headers are
present, OAuth validation is skipped and the raw token is used directly for that
session. This allows PATs and CI job tokens to be used alongside the OAuth flow on
the same server instance. `Authorization: Bearer` is always treated as an OAuth
token — use `Private-Token` for PAT-based header auth.
## Agent Skill Files
Pre-built skill files are available in [`skills/gitlab-mcp/`](./skills/gitlab-mcp/) for AI agents that support skill/instruction loading (Claude Code, GitHub Copilot, Cursor, etc.).
- **[SKILL.md](./skills/gitlab-mcp/SKILL.md)** — Core guide (~800 tokens) with toolset overview, key workflows, and parameter hints
- **[reference/](./skills/gitlab-mcp/reference/)** — Detailed workflow docs for code review, merge requests, issues, and pipelines
Install with the `skills` CLI:
```bash
npx skills add zereight/gitlab-mcp --skill gitlab-mcp-skill
```
Register the skill directory in your AI client to get optimal tool usage guidance without relying solely on the full ListTools response.

## Testing 🧪
The project includes comprehensive test coverage including remote authorization:
```bash
# Run all tests (API validation + remote auth)
npm test
# Run only remote authorization tests
npm run test:remote-auth
# Run all tests including readonly MCP tests
npm run test:all
# Run only API validation
npm run test:integration
```
All remote authorization tests use a mock GitLab server and do not require actual GitLab credentials.
